Assessing if walls are load-bearing?

[Arseface]

Hi, trying to determine if these walls are load-bearing, i.e., the walls marked in blue, yellow, and red. Can it be assessed from the drawing, or how should I proceed otherwise?

The house was built in 1975 and is a single-story house.

Where there are truss rafters (W), no interior walls should be load-bearing on the floor below, so red and blue should be okay to remove. It also depends on how it is resolved with the trusses where the two building sections meet. You need to go up in the attic and check.

Or is there a visible beam (either on the floors or in the attic) in the opening of the yellow wall, in the opening towards the entrance hall next to the yellow wall, and/or in the opening between the dining area and the hallway outside two bedrooms? Sometimes double lines are used for beams and sometimes for something optional, like a door.

You can hire structural engineers for these kinds of questions.

My interpretation is that there is a load-bearing beam at the dashed line between hall/dining area. Otherwise, no load-bearing interior walls.

Otherwise, there are no load-bearing interior walls.

Just because there is a double dashed line there or based on something else?
I want to learn more.

Where there are truss roof structures (W), no interior walls should be load-bearing on the floor below, so red and blue should be okay to remove. Then it depends on how it's resolved with the trusses where the two house sections meet. You need to go up to the attic and check.

Or is there a visible beam (either on the floor levels or in the attic) in the opening of the yellow wall, in the opening towards the entrance hall next to the yellow wall, and/or in the opening between the dining area and the hall outside two bedrooms?

You can hire construction engineers for these kinds of questions.

Thanks!

Thanks! The previous owners have opened up the yellow wall so as it stands now, there's something like a beam in the ceiling. However, it sounds hollow when I knock on it, so I'm uncertain if it's actually a beam or just aesthetic.

I will get back when I have had the chance to investigate further.

They probably covered the beam with drywall to make it look nicer.

If someone has bothered to install a beam with columns, it most likely means that the wall is load-bearing. Is there any building permit or approval registered with the municipality for that?

This is how it should be.

That's the way it should be.

Thanks!
So you mean that the wall between the dining area and what is called the hall outside the bedrooms as well as between the two smaller bedrooms is load-bearing. I thought you meant the wall between the dining area and the hallway by the front door, and I thought that was strange.
